Published Identifying a silicon transporter to improve the yield of rice



Researchers identify a membrane transporter in rice that regulates the accumulation and localization of silicon in the leaves.
Published Yeast with an over half synthetic genome is created in the lab



Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.
Published Scientists one step closer to re-writing world's first synthetic yeast genome, unravelling the fundamental building blocks of life



Scientists have engineered a chromosome entirely from scratch that will contribute to the production of the world's first synthetic yeast.
Published Scientists take major step towards completing the world's first synthetic yeast



A team of Scientists has completed construction of a synthetic chromosome as part of a major international project to build the world's first synthetic yeast genome. The work represents completion of one of the 16 chromosomes of the yeast genome, which is part of the biggest project ever in synthetic biology; the international synthetic yeast genome collaboration. The collaboration, known as 'Sc2.0' has been a 15-year project involving teams from around the world (UK, US, China, Singapore, UK, France and Australia), working together to make synthetic versions of all of yeast's chromosomes. Alongside this paper, another 9 publications are also released today from other teams describing their synthetic chromosomes. The final completion of the genome project -- the largest synthetic genome ever -- is expected next year.
Published Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks



Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.
Published Obesity linked to neurodegeneration through insulin resistance



Researchers have discovered a link between obesity and neurodegenerative disorders like Alzheimer's disease. Using the common fruit fly, the research shows that a high-sugar diet -- a hallmark of obesity -- causes insulin resistance in the brain, which in turn reduces the ability to remove neuronal debris, thus increasing the risk of neurodegeneration.
Published 'Biodiversity time machine' provides insights into a century of loss



AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published Plants' ingenious defense against mutational damage



How do plants deal with mutations in their 'power stations'? By exploiting randomness to create diversity, say researchers.
Published Threatened sharks and rays caught off Cyprus



Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Published Some benefits of exercise stem from the immune system



Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging.
Published New antibiotic approach proves promising against lyme bacterium



Using a technique that has shown promise in targeting cancer tumors, a team has found a way to deploy a molecular warhead that can annihilate the bacterium that causes Lyme disease.
Published Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence



Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.
Published To restore ecosystems, think about thwarting hungry herbivores



Re-establishing plantings of trees, grasses and other vegetation is essential for restoring degraded ecosystems, but a new survey of almost 2,600 restoration projects from nearly every type of ecosystem on Earth finds that most projects fail to recognize and control one of the new plants' chief threats: hungry critters that eat plants.
Published Female sex determining gene identified in mice



Researchers have identified a gene which is an early determining factor of ovary development in mice.
Published A known environmental hazard can change the epigenetics of cells



An international team of researchers has discovered that formaldehyde, a widely spread pollutant and common metabolite in our body, interferes in the epigenetic programming of the cell. This finding expands the knowledge of formaldehyde, previously considered only as a DNA mutagen, and helps establishing a further link with cancer.
Published Research connecting gut bacteria and oxytocin provides a new mechanism for microbiome-promoted health benefits



Researchers found that the hormone oxytocin, known to be involved in regulating feeding and social behavior and until now to be produced mostly in the brain, is also produced in the human intestine. Furthermore, gut resident bacteria L. reuteri can affect the production of gut-made oxytocin, providing the first insights into a mechanism by which these bacteria can influence human health.
Published Immunology: Dysfunction of mitochondria drives the exhaustion of T cells



In the immune system's fight against cancer and infections, the T cells often lose their power. Now immunologists may have found a possible explanation for this phenomenon.
Published New study sheds light on the molecular mechanisms underlying lipid recycling within cells



Our understanding of how cells recycle lipids through autophagy -- a form of cellular degradation -- has grown significantly, thanks to a recent study. Using yeast as a model organism, the researchers explored the molecular mechanisms leading to the degradation of the phospholipid bilayers making up the cell membranes. Their findings improve our understanding of cellular degradation processes and related metabolic disorders.
Published First mice engineered to survive COVID-19 like young, healthy humans



Researchers have genetically engineered the first mice that get a human-like form of COVID-19, according to a new study.
Published Plastic-eating bacteria turn waste into useful starting materials for other products



Mountains of used plastic bottles get thrown away every day, but microbes could potentially tackle this problem. Now, researchers report that they've developed a plastic-eating E. coli that can efficiently turn polyethylene terephthalate (PET) waste into adipic acid, which is used to make nylon materials, drugs and fragrances.
